Honda Engine Block - Cast Aluminum

[engnerdan]

I got a call last week about welding an engine block. I assumed it was cast iron but figured I would check it out. Much to my surprise it was aluminum, this hole was formed when a boss that is cast on the block got pulled away by the exhaust manifold. I was originally going to weld a plate in, but once the boss was moved out of the way I decided to just weld it up. I welded the hole shut, cleaned it up and laid a second layer on top of it.

Did this repair with my Dynasty 200, coolmate 1, 2% lanth 1/8", 150hz 72%. Total repair time from arrival to packed 2 hours.
